Reinhard's definition of "sweets" has always been "something whose principal source of calories is sugar". If a teaspoon of sugar in a coffee is fine, then a teaspoon of honey on your porridge is fine. It's not "made entirely from sugar" if the honey is on top of a bowl of oats. If you're eating the honey straight from the spoon, well, sure...

Another simple test he suggests is "would you eat this for dessert?".

For these borderline foods, everyone will draw their line at a different place - if you find you are ladling on several tablespoons of sugar and honey, and doing it every day, you might decide to make that an S.

In general when you first start, I'd say worry about the main rules - not eating between meals, only eating one plate, and staying away from obvious sweets like cookies, candies, puddings, cakes, etc. Once you've got those habits sorted out, and you are finding them second nature, then you can decide whether you're happy where you are, or whether you want to go after those "1%" items.
